EVALUATION GUIDE
How to evaluate a device intelligence vendor.
Eight questions, with our answers and where to check them.
The eight questions
| Question | Why it matters | Our answer | Check it |
|---|---|---|---|
| 01Does each verdict show its reasons? | You will have to explain declines to customers and auditors. | Yes. | Live check |
| 02Does it say “unknown” when it does not know? | A silent gap looks like a clean result. | Yes, for residential proxies today. | Network risk |
| 03Can you set your own thresholds and rules? | Your risk appetite is not the vendor's. | Yes. Rules on your signals that block an identification sent from your server, or return a challenge or a flag. In the browser, a match blocks only once you turn on rule enforcement there. | Platform |
| 04Is pricing published? | Hidden prices mean you cannot compare costs before you talk to sales. | Yes. | Pricing |
| 05Can you test it on your own traffic before you pay? | A demo is not a test. | Yes: after a demo call, your account starts with a 90-day free trial with no card. The live check on our homepage runs on your own browser with no account. | Book a demo |
| 06Is the verdict fetched on your server? | A browser can be tampered with. | Yes, with your API key. | Server API |
| 07Which browsers does recognition hold across? | “Cross-browser” often means one engine. | Browsers that share an engine, such as Chrome and Edge. Matching across engines is in evaluation and off by default. | Device identity |
| 08Do they publish accuracy, with a method? | A number without a method is marketing. | Not yet. We quote no figure until we have measured one. Measure us on your own traffic instead. | Evaluate on your traffic |
